This class includes:
(A) Compositions which are:
(1) Explosive; explosive compositions for the purpose of thisclass are those containing both a fuel and sufficient oxygen oran oxidizer so that, upon initiation, they are capable of undergoinga chemical change at a relatively high rate of speed, or a speedapproaching instantaneous, resulting in the production of usableforce through chemical change in the composition to produce gaseousproducts and usually heat, and are used for blasting, firearms,jet propulsion of rockets, vehicles, etc., rapidly filling automotivepassenger-restraining gas-bags, etc. See Glossary, below.
(2) "Thermite"; "Thermite-type" compositionsfor the purpose of this class include; (a) a consumable fuel componentwhich is any of metal (alloy and intermetallic compounds), metal-metalloidcompounds, metalloids, and hydrides of metals or metalloids; (b)and in combination therewith an oxidant component which is eithera metal oxide, inorganic oxygen salts and organic metal salts capableof yielding a metal oxide on decomposition, which components, dependingupon the manner reacted, produce quantities of heat and chemicalby-products, either solid or fluid which by-products may be recoverable.These compositions, by way of examples, are employed to produceusable heat and light, chemical products and especially metals,in pyrotechnics and incendiary, match compositions and smokes andfor explosive priming or as additives for explosive compositions.
Included within this definition are unreacted mixtures of metalswith metalloids because, though they contain no oxidant, they neverthelessreact similarly to "Thermites" to yield usableheat. Also included are thermite compositions which contain an additivedesigned to prolong heating effects, reduce the production of gasor other by-products or otherwise moderate the exothermic activity ofthe composition.
(3) Fuel specialized for jet-rocket engine and intended forreaction with an oxidant therein, excluding air, in order to providethrust for motive power purposes.
(4) For use in neutralizing the poisonous gases of explosives.
(B) Methods of preparing or treating such compositions nototherwise provided for. The classification of processes is basedupon particular components of the explosive or thermic composition.
